ABSTRACT:
A process for joining components made of metal, in particular aluminum and aluminum alloys, is such that a thermally-curable (hardenable) adhesive is deposited between the close-fitting surfaces of the components that are to be joined, and one of the outer surfaces neighboring the said close-fitting surface of one of the components is radiated with infra-red radiation in order to cure the adhesive. At least the outer surface to be radiated is provided with a pattern that roughens that surface. By reducing the reflectivity of the roughened surface the capacity to absorb infra-red radiation is increased. A preferred application for the process is in the adhesive bonding of shaped parts, especially body sheet in automobile manufacture.
